What Cindi said. If it takes me more than a day to do a quilt, I'll get to the bottom border & then wonder what the heck I did on the top. I'm sort of a Rambo quilter & don't mark much, just sort of go with it. I know that some quilters are talented enough where they don't have to turn the quilt to get the side borders, but if I'm doing something wavy, like a long feather, I have to turn it. I do the sashing as I go, although sometimes I wait until the end & go back & fill in the sashing, but I've never done blocks larger than the depth of my quilter, so I can get all those without turning.
